To all whom it may concern:

Be it known that 1, CHARLES Josnrn EsoALA'N'rii, a citizen of Mexico, and a resident of the city of Merida, State of Yucatan, Republic of Mexico, have invented a new and, Improved Spring Suspension for Automobiles, of which the following is a full, clear, and exact description.

This invention relates to vehicles, and" deals particularly. with spring suspension systems for automobiles.

The invention has for its general objects to improve and simplify/the construction of vehicle body springs whereby the maximum smoothness of running and comfort to the occupants are obtained by a novel, simple and inexpensive arrangement of springs;

A more specific: object of the invention is p the provision of a novel arrangement of springs which are pivotally connected with the frame and suitably connected with the axles, in combination with a spring fastened to the frame and having its free ends shackled to the first-mentioned springs adjacent their pivots, whereby the up and down movement of the said first-mentioned springs with the wheels and axle causes the spring to be flexed so as to yieldingly resist said relative movement of the wheels and body, whereby smooth and easy suspension of the body is obtained and the wheel s'are maintained in eliminatin bouncing, reboundingor jolts.

One of t e principal objects of the invention is to provide means, in connection with the side springs connected with the axles and pivotall connected with the vehicle y, whereby rebounding 1S reduced I to a minimum, this being accom lished by employing a third spring which has its ends connected by novel shackling means with the side springs adjacent their pivoted ends so that the ends of the third,

spring "yield to a less extent than the movement of the side springs.

With such objects in view, and others which willa appear as thedescription proeeeds,"the iifvention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompany1ng drawings, which illustrate one embodiment of the invention Specification. of Letters Patent.

wherein similar characters of reference indicate corresponding parts in alltthe views, Figure 1 is a longitudinal section of a chassis embodying the improved spring suspension system;

Fig. 2 is a plan View of the chassis;

Fig. 3 is an enlarged sectional view of one v end pf the chassis; Fig. 4 is a plan view of Fig. 3;

Fig. 5 is a perspective View of one of the members of the shackle.

Referring to the drawing, 1 designates the side bars of thefrarne' of an automobile, 2 the axles and 3 the wheels.

Between each set of wheels and the body is a spring suspension composed of a pair of quarter elliptical leaf springs 4 and a single semi-elliptical spring 5, which springs are connected with the side beams l of the vehicle frame by a specialform of shackle means compose of a coupling member 6, interlaced links 7, and a stud 8. The s rings 4 extend'parallel with the sides of t e vehicle frame and have their ends 9 rigidl fastened to the axle. The butt end'of sec quarter elliptic spring is disposed in a box 10 which forms the body of the coupling or shacklememberfi. This box has an upper eye 11 which receives the'horizontal stud 8 projecting outwardly from the side bar 5 or beam 1, and also. on the box 10'is a dc pending arm 12 terminating in. an eye 13, to which is pivotally connected one of the links '7.- Each spring 5 is-rigidl fastened to the vehicle-body by braces M astened to the enter of the semi-elliptical spring 5" and to the side bars 1; The outer ends of the spring 5 terminate in eyes 15 to which one of the links 7 is pivotally connected- The springs 4 swing in a vertical plane and connection with the accompanying drawing, the advantages of the construction and method of operation will be'readily' understood by those skilled in dhe art to which the invention appertains,f'and While I have described the principle of operation, together with the structure which I now consider to be the best embodin'ientthereof, I

desire to have it understood that the, strucp 10(- From the foregoing descriptiongtaken in ture shown is merely illustrative and that such changes maybemade when desired as fall within the scope of the appended claims.

Having thus described, my invention, I

claim as new and desire to secure by Letters 4 between the pivots thereof and'sa'id axle.

2. The combination of a vehicle frame, an axle, Wheels on the axle, quarter elliptic springs pivotally connected with the frame and connected with spring mounted transversely on ,the frame with its outer ends free, and shackle means connecting the free ends of the transverse spring to the first-mentioned springs at points adjacent the pivots-thereof and between the pivots and axle.

3. The combination of a Vehicle frame, an

axle, Wheels on the axle, quarter elliptic springs havingtheir free ends connected with the axle, a coupling member to which the other end of each springis fastened, a

pivot between the couplingmeniber and the vehicle frame, a link connected with each coupling member, and a horizontal yielding spring fastened on and disposed under the frame and connected with the links.

4. The combination of a' vehicle bod an axle, wheels on the axle, vertically yie ding s rings connected withthe axle and pivota ly connected with the frame, and horizon tally yielding spring means on and disposed under. the frame at a point inwardly from the wheels and linked to the first-mentionedv springs at points adjacent their pivoted ends.

the axle, a semi-elliptic of the springs with the sides of'the a transverse spring 7 disposed under the vertically yielding quarter elliptic springsv connected.

fastened tothe axlesand pivotall with the frame, horizontally yie ding semielliptic springs disposed-transversely to the frame, means for rigidly fastening the center of each semi-elliptic spring to the frame, and connecting means between the outer ends of the semi-elliptic springs and the first-mentioned sprin s at points adjacent the pivots thereof and iietween the latter and axles.

6. The combination front and rear axles,

of a vehicle frame, wheels on the axles,

springs connected with the axles and extendf mg inwardly toward the center of the frame,

means'pi'votally connecting the inner ends frame,

frame at a pointinwardly from each axle, and flexible means connecting the outer ends of the transverse springs with the adjacent tending inwardly toward the center of the 4 frame, means plvotally connecting the inher ends of the springs with the sides of the frame, a transverse spring disposed under the frame at a point inwardly from eachaxle, a link vertically pivoted to the outer end of each transverse spring and extending outwardly therefrom, a coupling connected with the pivoted .endof each of the first-mentioned springs, and a link horizontally pivoted to each coupling at a point under the associated spring and connectedwith the adjacent link of the transverse.
